Things I've built on the side
Investify
One screen for every stock I follow: charts with technical signals, SEC financials, earnings, news and social sentiment. Claude reads it all and writes a short brief for each ticker.
Conflux
A co-op roguelite for up to four players. You fight room by room and mix fire, frost and lightning into combos, with Windows, Android and iPhone players in the same party.
BrimMate
Where to stand and what to aim at to land a smoke or a molly on any Valorant map. Lineups come from players, who vote on the ones that actually work.
Storyweaver
A story that bends around your decisions. It remembers what's in your pockets and who you've annoyed, and the options you get depend on both.
Portfolio Assistant
Type in what you hold and it plots your mix against thousands of random ones. You can see where the efficient portfolios sit, and how far off yours is.
